25. Zone 2 Manual N Summary

26. Field Notes
For many buildings the ducts are located in an unconditioned space. Thus, the Manual N Speedsheet default setting of T, or the actual duct size can be entered to calculate the heat loss/gain. However, to use the Speedsheet for duct inside of the conditioned space, where the ducts have been previously filled in: to remove the #N/A simply change the T or square foot values to 0.
